In that case the idea of using the analogue inputs to drive a
frequency output into an encoder channel is probably more robust.
it is nearly as simple as
void setup(){
pinMode(0, OUTPUT);
}
void loop(){
float v;
v = analogRead(0);
tone(0,v); // Output the square-wave on pin 0 1024 HZ = 5V
}

If you can't fix it, you don't own it.
